A new and strong move.
13... f8e8  14. h1e1  14... h7h6  15. g5h4 The moves from both sides are the most natural after 13.Qe2. One question I have here is whether Black can play g7-g5 to get out of the pin. This is always a difficult move to evaluate in this type of position, leaving us to wonder whether it's worth weakening the kingside and if White can sac the knight on g5. 15... d5d4
